Festo
33185
Air solenoid valve MFH-5-1/4-L-S-B
The Festo part number 33185 is an electrical 5/2-way monostable industrial component featuring a piston gate valve structural design with a 32 mm width dimension, a 10 mm nominal width, and a normal nominal flow rate of 1600 l/min normalized to DIN 1343. Operating within a pressure range of -0.09 MPa to 1 MPa (-0.9 bar to 10 bar) and utilizing a G1/4 pneumatic working port, this piloted unit incorporates an external pilot air supply port, adjustable exhaust air function, soft sealing principle, positive overlap lap, and a pneumatic spring reset method. Additional attributes include any mounting position, non-detenting manual override, reversible flow direction, and a pilot pressure range of 0.3 MPa to 1 MPa (3 bar to 10 bar).
